Title: Method and device for detecting position
Inventor: NAKAGAWA YASUO
IPC: G01B11/00
Filed: 1982-02-19
Abstract: PURPOSE:To ensure the detection of the position of an object body or an object part having a special shape, by detecting a cross shaped light beam irradiated on a plane, on which the object body is mounted as a reference plane, or on the surface in the vicinity of the object part. CONSTITUTION:The circular cylinder shaped object body 15 is mounted on the plane 14, and the cross shaped light beam 15 is irradiated on the object body 15 from the direction approximately directly upward. The light from a lamp 1 becomes the cross shaped light beam through a condenser lens 2, a cross slit 3, and a light projecting lens 4, and irradiated on the upper surface of the object body 15 and the plane 14. In this case, it is sufficient that the intersection of the cross shaped light beam is located at the arbitrary position of the upper surface of the object body 15. The intersection is not necessarily required to be located at the central position of said surface. The position of the object body 15 can be detected based on the irradiated state of the cross shaped light beam on the plane 14 as reference plane and the object body 15.

Filed: 1988-02-04
Abstract: PURPOSE:To reduce the unused part in a used film and to secure the transfer of the film by detecting the boundary of the colored part and uncolored part of the test film optically and stopping the transfer of the film. CONSTITUTION:The test film 31 is transferred to an analytic area 4, liquid to be inspected is spotted on the film 31 from a spotting nozzle 3 and incubated by an incubator 6, and a measuring instrument 7 measures the optical density of the colored part. A motor M is driven after the measurement to move the film 31.
